Theembodiment was chosen and described in order to best explain theprinciples of the invention and the practical application, and to enableothers of ordinary skill in the art to understand the invention forvarious embodiments with various modifications as are suited to theparticular use contemplated.

System 100 performs a process for determining an area where images (forobjects) should be placed such that they account for a user's (for auser 102) line of sight 127 a through a transparent display apparatus104 (e.g., a window, a heads up display (HUD), etc). Line of sight isdefined herein as including all equivalent information to a line ofsight and/or information capable of deriving a line of sight. Forexample, a line of sight may be calculated to determine image placement.Alternatively, a line of sight may include a set of processedmeasurements for producing a location of image placement.

System 100 includes user facing devices (or cameras) 112 a and 112 b andobject facing devices (or cameras) 110 a and 110 b attached to displayapparatus 104 and connected to a computing system for processing. Userfacing devices 112 a and 112 b identify a relative special position ofthe user's eyes with respect to display apparatus 104. Object facingdevices 110 a and 110 b simultaneously identify an object(s) spacialposition on an opposite side (i.e., from user 102) of display apparatus104.

System 100 enables a generic pattern recognition process with respect tofacial features via a user facing devices 112 a and 112 b (e.g.,recognition of relative positions of anatomical features including,inter alia, eyes, ears, nose, etc.) to triangulate a relative eyeposition in order to infer line of sight information. System 100 maydetermine the angle and distance of a user's eyes/face from itself usinguser facing devices 112 a and 112 b via paths 115 a, 116 a, 115 b, and116 b, respectively. The various spacial positions are used to determinea position of an image presentation on display apparatus 104 relative toviewable objects (e.g., object 108) from a perspective of user 102.Additionally or alternatively, the image presentation may include anillumination of display apparatus 104 (e.g., an image projection, animage reflection, an image hologram, etc).

System 100 includes transparent display apparatus 104 (includingtransparent displays 104 a and 104 b) that includes user facing devices112 a and 112 b and object facing devices camera 110 a and 110 bconnected to a computing system for discerning a user's 102 relative eyeposition and for discerning an object's 108 relative position withrespect to display apparatus 104. Display apparatus 104 may include anytype of display apparatus including, inter alia, windows, an HUD, etc.System 100 allows image selections to be made by a relative position ofa display apparatus, user, and object irrespective of an angle orgeometry of the display apparatus.

System 100 includes multiple fixed user facing devices (i.e., userfacing cameras 112 a and 112 b) enabling a triangulation process fordetermining the user's relative position. Additionally, multiple objectfacing devices (i.e., object facing devices 110 a and 110 b) enable atriangulation process with respect to objects such that an accurate lineof sight (i.e., line of sight 127 a) may be determined. Theaforementioned information may be used to determine where to displayinformation (on display apparatus 104) relative to user 102. Forexample, with respect to transparent glass capable of displaying data,forward and rear facing devices (e.g., user facing devices 112 a and 112b and object facing devices 110 a and 110 b) in combination with acomputing system determine where to display data on the transparentglass such that the data appropriately overlays a scene behind thetransparent display. As an example, a ship's bridge could use theaforementioned information to overlay information on landmarks,deckhands, or detected objects on its windows such that a user wouldhave an accurate representation of where these objects are, irrespectiveof the user's position on the bridge. As a second example, with respectto a windshield capable of dimming in select areas, sets of forward andrear facing devices may determine which portions of a windshield shouldbe dimmed such that bright objects may be attenuated from a user'sperspective, regardless of where the user is positioned relative to thewindshield.

An implementation example enabled by system 100 allows a user 102 tolook through a set of windows (i.e., display apparatus 104 shaped asrounded rectangles) from two different angles (i.e., a first positionillustrated in FIG. 1A and a second position illustrated in FIG. 1B).Object and user facing devices (i.e., user facing devices 112 a and 112b and object facing devices 110 a and 110 b) interpret the locations ofboth user 102 and an object 108 relative to the windows (i.e., via lineof sight 127 a or 127 b). Using the interpretation of the locations, anarrow 108 a may be displayed on an appropriate area of the window suchthat user 102 is able to view arrow 108 a overlain and accuratelypointing to object 108 along line of sight 127 a or 127 b. Additionally,the forward and user facing devices may account for a vertical offset ofboth user 102 and object 108. Additional images related to objects maybe simultaneously displayed in position relative to user 102 andrespective objects.

Additionally, symbols describing relationships between objects may beenabled. Relationships may include, inter alia, a distance between twoobjects, etc. The following implementation example describes a processassociated with symbols describing relationships between objects:

A display system installed on a crane may display information associatedwith a location of a lifted load relative to the ground. The displaysystem retrieves and combines information associated with the locationof the lifted load and a geometry of the ground resulting in a box(being displayed) indicating a location on the ground that the load ispositioned above.

FIG. 2A illustrates a first object facing internal logic view/objectimage 205 of a computing apparatus for determining a line of sightbetween a user and an object for image placement on a transparentdisplay apparatus, in accordance with embodiments of the presentinvention. Internal logic view/object image 205 illustrates a retrievedimage of objects 207 and 208. An image of an object may be created usinginformation from any type of sensor that may convey information toidentify a specific position. For example, in the aforementionedimplementation example, an image of an object may include a measurementof a boom angle and a length of a cable supporting a load. Additionally,note that the determination of the load-ground system as a first object,with measurements of boom angle and cable length comprising the object'skey features may be “hard coded,” (i.e. the display system may bedesigned/configured to process a set of specific measurements withoutdetermination at runtime). Prior to, simultaneously, or subsequent tothe process enabled by internal logic view/object image 205, a relativelocation of a user is determined. The determination of a relativeposition of a user is described in detail with respect to FIGS. 4A-4C,infra.

FIG. 2B illustrates a second object facing internal logic view 205 a ofthe computing apparatus for determining a line of sight between a userand an object for image placement on a transparent display apparatus, inaccordance with embodiments of the present invention.

Additionally, a relative angle(i.e., represented by line 212) and distance to the object facing deviceis determined. The distance may be determined by additional informationpassed by the object facing device to a processor of the computingapparatus. For example, a radar that determines a distance as well as anangle, a stereoscopic image that is processed to determine a distance ofobject 207. Information relating to object 207 is retrieved for imageplacement on a transparent a display apparatus. Additionally, a symbolor text associated with object 207 may be generated for image placementon the transparent display apparatus.
